Activity at Mexico’s most famous volcano seems to be picking up over the last few months. This week saw another ~3 km / ~10,000 ash plume from Popocatépetl and CENAPRED has been reporting increasing seismicity at the volcano. There has also been consistent glow at night from the summit region – all signs that magma is very close to the surface. You can see some footage of this eruption and evacuations in an oddly captivating Indian news story (that seems to have gotten a little carried away with the use of moving arrows and zooms). CENAPRED’s latest report has Popo on Yellow Alert status and they expect more small explosions like the one from this week to continue. There is a 12-km radius around the crater that has now been declared “off limits” The viewing isn’t great right now, but you can also watch Popo via webcam as well. In another story related to Popo, the volcano has apparently now lost 5 of the 7 glaciers that used to be hosted on its edifice. This might seem inconsequential, but many of the local communities near the volcano rely on the runoff/meltwater from these glaciers for their drinking water, so the loss of the glaciers could have implications in local water.
